Propaganda is what it is. There's a strong astroturfing machine dedicated to making the right look ridiculous by either promulgating absurd conspiracy theories, or dredging up genuine elements of the fringe and popularizing them. For example, during the vaccine controversy, the right didn't get any chance to put forth any reasonable good faith concerns about the virus, because all you could hear was bullhorns shouting autism, 5G, microchip implantation, and deliberate mass genocide theories.
It's a brilliant strategy because it drowns out legitimate opposition and also anyone on the fence or unsure will decide not to associate with the anti-vax movement even if they otherwise might have.
As always the right gets played like a fiddle this way and haven't figured out how to turn the tables or even figured out they're being played... often they just jump to defending the crazies.
Similar things are happening now by dredging up and harping on the worst elements of anti-abortion laws, with the same exact goals and results.
